annular-CONNECTING DEVICE;

Application-filedOctober 22, 1927. Serial No. 227,923. g

My. invention relates to means fol-establishing connection between thehose leadlng .from a tire pump and a tire valve for use in inflatingtires.

provide a new and. improved connection means for the stated purposewhereby they connection with the tire, valve may be established in theminimum time and'with max imum facility while at the'same time effectingafirm and efiiclent' connection.

The nature of my invention and its distinguishing features andadvantages will be more clearly understood as the description a Vcounterbore of said. sleeve and hearing at ;70

proceeds.

Reference is to be had to the accompanying drawings forming a partof'this specification, it being understood that the drawings are merelyillustrative of one example'of the invention.

Figure 1 is a view partly in longitudinal section and partly inelevation showing my improved connecting device applied to a hose and toa tire valve, both shown inpart, the connecting device being shown inthe form before securing it to the tire valve Figure 2 is a transversesection on the line 2-2 of Figure 1; a

Figure 3 is a view similar to Figure 1 bu showing the connecting devicead usted into gripping relation with the the valve;

Figure 4 is a vertical sectionon line 4,4 of Figure 3; I p y Figure 5 isa longitudinal sectional view of a portion of the hose and its nozzle,the view being given to illustrate the manner of disassembling theconnecting device, as, for

example, when the rubber valve-gripping bushing is to be renewed orreplaced;

Figure 6 is a section on Figure 5; and I Figure 7 is an elevation of theshell or casing of the connecting device, the view heipg given to showthe form of slot in'said siell.

In carrying out my invention in practice in accordance with theillustrations, a shell or casing 10 is provided having a slot 11 formedwith an enlarged end 12, the preferred form of slot being that of a keyhole slot. The forward end of the shell 10 is formed. with a flange 13directed radially inward to present a restricted opening for theentrance of the threaded nipple a of a tire valve A.

The general object of the invention is to the line 6-6 of A cylindricalplug or body portion 14 is .provided'in the shell 10 and has on the sidethereof a threaded hole 15 so that-thethreaded end 16 ofa nozzle 17 ofan airhose 18 can be tapped into said plug 14. A sleevef19 is providedon the nozzle 17 and formed with amilled surface for the turningyofsame; The front terminal or nipple 21 of sleeve '19 is adapted to bindagainst theflattened side 200i the plug 14 after said terminal 21 has Ipassed'transversely through the slot 11 of shell 10. A spring22 isprovided on nozzle 17 within the sleeve 19, said spring bearing atoneend against theshoulder 24 of the its opposite end against shoulder 23on' nozzle 17. The numeral 26 indicates a. longitudinal. air passageinplug 14 communicating with the nozzle 17-when the threaded end 16 ofsaid nozzle is engaged with thread 15 of plug 14. i i The threaded endor nipple a of tire valve A is adapted to be firmly gripped by a re--silient bushing 27 in the shell 1 10 in front of theplug 14. I I

It will be observedthat the terminal or 7 reduced end 21 ofthesleeve 19has an'eccentrio bore through which the "stem;17 passes, so that saidterminal 21 constitutes a camy Said cam21 lies in the slot 11 and isadapted to bear against the shell '10 at the enlarged end 12 of saidslot,: as indicated in Figures' '1 and 3. The arrangement is such thatthe "sleeve 19may be turned in the enlarged end'.

12ina manner to cause the shell 10 to move in such a'direction as willbring the flange 9 13 a less distance from theyadjacent end of the plug14, whereby. the resilient bushing 27 will be compressed'and theyborethereof constricted's'o as to bind onthe threaded nippleaof valveA, whereby to firmly bind the ,9

device onthe said valve nipple. Or, the cam 21. may be turned in amanner to move shell 10 ina direction to cause the flange 13 to relievethe pressure on bushing 27 thereby releasing valve nipple'a, When it isdesired to disme'mberthe connecting'device consist-- ing of the shell10, plug'14, and resilient bush ing 27 itis only'necessary toslidethesleeve 19 rearwardly'on the nozzle 17 of the air hose 18. Thisrearward sliding of the sleeve 19 compresses spring 22 and withdraws theterminal 21 from contact with the flattened side 20 and out of slot 11,whereby the nozzle 17 With sleeve 19 thereon may be moved lengthwise ofthe slot 11 toward the outward-end thereoi and carry with it the plug14, allas will readily be understood from an examination of Figure 5.Vith the plug removed bushing 27 may be renewed;

It will be readily understood that. withthe device constructed and'l'unctioning as described, a fastening of the connecting device to thetire valve can he cilected very quickly.

-Moreover it will beseen that the device is of body of the connectingdevice in order to lock orfasteirit to a tire valve Ti lie device doesaway with all levers for the turning, of?

which there is in some wheels no clearance for the lever and the lockingand binding of the: connecting device to the tire valve. AZ furtherpoint of advantage of the above-described connectingdevice isthat.thefasten"- ing of the said. device toa tire valve does not always takeplace at precisely the same point. With most makes of connecting devicesfor the purpose the lover or other part which does the fastening to. thetire valve must' alwaysbe turned to the same identical point be-fore'the connection with the tire valve is fully established. Zith myimproved construction the naturalwear fromuse of the rubber bush ingunder an ordinary amount oiwear,;or a

slight variation in the nipple or threaded terminal of the valve stemwill notprevent:v

the. att chment of the connecting. device'in a manner to hold itsecurely to the valve un-= der several. hundred pounds air pressure;

It will be. further realized that my im-- proved connecting devicerequires no tools for dismemberingthe device or for changing. theresilient bushing. Itwill be: apparent iiurtherinore that the describedassemblage makes for compactness.

1 would state fillilhGl'll'lOlG that while the illustrated exampleconstitutes a practical embodiment of my inventiomldo not limit myselfto the exact details herein illustrated, since, manifestly the same canbe considerably varied without departure from the spirit of theinvention as defined in the appended claims; e
